Bell & Gossett 1BL033 PL-55 Pump 2/5 HP Motor 230V

230 V commercial hydronic systems can evaluate the Bell & Gossett 1BL033 PL-55 with 2/5 HP single-phase power, cast-iron construction, standard mechanical sealing, and maintenance-free oil-lubricated bearings for high-resistance piping networks.

The closed-loop body material separates this model from bronze open-loop circulators, making fluid application an important selection boundary. The supplied record identifies electrical voltage and application context, but does not provide exact flow, head, NPSH, pressure, temperature, or efficiency data.

Product Features

- The 2/5 HP motor establishes the listed power class for commercial hydronic planning.
- 230 V single-phase operation requires compatible branch-circuit and motor-control provisions.
- Cast-iron construction identifies the documented body material for closed-loop systems.
- Standard mechanical sealing provides the stated seal arrangement for service-part review.
- Maintenance-free oil-lubricated bearings identify the documented bearing configuration.
- High-resistance piping networks provide the listed application context for equipment evaluation.
- The PL-55 designation identifies the selected circulator model for replacement comparison.

Hydraulic Performance and Application

230 V commercial hydronics and high-resistance piping networks are the documented applications for this PL-55 configuration. Exact flow, head, NPSH, pressure, temperature, pump curve, and efficiency values are not supplied, so the 2/5 HP rating cannot replace duty-point verification.

Installation Requirements

Confirm 230 V single-phase power, closed-loop fluid conditions, piping compatibility, flow direction, rotation, seal access, bearing configuration, and service clearance before installation. Cast-iron construction should remain within the approved closed-loop application, and operating conditions must follow the applicable manufacturer requirements.

Warranty and Maintenance

Bell & Gossett provides an 18-Month Limited Warranty from installation or a maximum of 3 years from the product date code, whichever occurs first, for Series PL boosters. Coverage addresses material and workmanship defects, while improper installation, misuse, alteration, negligence, and contrary operation are excluded. The oil-lubricated bearing arrangement remains a service consideration. Mulmotor provides pre-purchase support.
